论文摘要
超轻标量暗物质可能会引起恒星质量的明显振荡，可以通过穆恩原子和muonic原子光谱中的时间移动直接探测。现有的数据集和持续的光谱测量值能够探测比天体物理范围更严格的标量 - 穆恩相互作用。持续使用Muonium的自由落体实验可以探测与Muons和标准模型颗粒之间虚拟超轻标量玻色子交换相关的力，从而高达5个数量级的敏感性比互补实验室和天文学界限提高。
Ultralight scalar dark matter may induce apparent oscillations of the muon mass, which may be directly probed via temporal shifts in the spectra of muonium and muonic atoms. Existing datasets and ongoing spectroscopy measurements with muonium are capable of probing scalar-muon interactions that are up to 12 orders of magnitude more stringent than astrophysical bounds. Ongoing free-fall experiments with muonium can probe forces associated with the exchange of virtual ultralight scalar bosons between muons and standard-model particles, offering up to 5 orders of magnitude improvement in sensitivity over complementary laboratory and astrophysical bounds.
